getterThisX
```
public static Expression getterThisX(ClassNode annotatedNode,
                                     PropertyNode pNode)
```
This method is similar to propX(Expression, Expression) but will make sure that if the property being accessed is defined inside the classnode provided as a parameter, then a getter call is generated instead of a field access.

Parameters:

annotatedNode - the class node where the property node is accessed from

pNode - the property being accessed

Returns:

a method call expression or a property expression

getterX
```
public static Expression getterX(ClassNode annotatedNode,
                                 Expression receiver,
                                 PropertyNode pNode)
```
This method is similar to propX(Expression, Expression) but will make sure that if the property being accessed is defined inside the classnode provided as a parameter, then a getter call is generated instead of a field access.

Parameters:

annotatedNode - the class node where the property node is accessed from

receiver - the object having the property

pNode - the property being accessed

Returns:

a method call expression or a property expression

convertASTToSource
```
public static String convertASTToSource(ReaderSource readerSource,

                                 throws Exception
```
Converts an expression into the String source. Only some specific expressions like closure expression support this.

Parameters:

readerSource - a source

expression - an expression. Can't be null

Returns:

the source the closure was created from

Throws:

IllegalArgumentException - when expression is null

Exception - when closure can't be read from source
